Beyonce tears up while accepting Vanguard Award from Jay Z at VMAs

Beyonce, Jay Z and their adorable daughter, Blue Ivy, sure looked like a happy family at the MTV Video Music Awards on Sunday night despite ongoing reports of marital trouble.

Beyonce wrapped the VMAs with a nearly 20-minute non-stop, energy-filled performance, which found her sporting a metallic leotard while running through several songs and showing off her vocal chops.

At one point, she included a special dedication for her fans.

"This next song is for my fans. If it wasn't for you guys I wouldn't be here on this stage," she said before launching into "XO."

Throughout her performance, the camera panned to Jay Z and Blue Ivy who watched from the audience -- singing and dancing along. That was pretty darn cute. But the best (and most unexpected moment) came when Jay Z appeared onstage with Blue Ivy to present Beyonce with the Michael Jackson Vanguard lifetime achievement honor. Right then and there the singer began to get emotional, fighting back tears as she accepted the award.

Jay Z called his wife, "the greatest living entertainer." Meanwhile, online GIFS show Blue Ivy clapping onstage and saying what appears to be "Yay Mommy." Aw.

"I'm so full. I have nothing to say...but I am filled with so much gratitude," Beyonce said onstage before telling Blue Ivy she loved her.

"My beloved, I love you," she said looking at Jay Z. "MTV I love you."

Beyonce, after Sunday night -- we're convinced the world loves you.
